Results indicate that the sum of the molar ratio of hydroxide to aluminum and the molar ratio of fluoride to aluminum (γOH+F) governs the defluoridation with aluminum salts. In electric kinetic experiment, the results indicate γOH+F can also be used as the key parameter and sulfate or other multi-valence anions influenced the system most because they rise the anodic over-potential. A variable order kinetic model can be used to simulate the defluori-dation in EC. The flotation of SS in EC is successful with adding appreciate amounts of SDS.application/pdf56933 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所電膠羽浮除法化學沉降法氟 離子electrocoagulationcalcium precipitationfluoridereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22111/1/912211E002027.pdf
